IDEAL INDUSTRIES 4330129847 30-1065S Twister Al/Cu Conn, 1 Pack

These are great for homes that have old aluminum wiring. The twister have penatrox inside, so no mess!

Working well.

I am an electrical and lighting engineer. Most new light fixtures use aluminum instead of the traditional copper which is used in existing houses. Why you ask? Aluminum is cheaper. BUT that complicates things & the importance of this wire-nut cannot be overstated. When you have the termination of two different materials you need to use the proper protection. This wire-nut emits a clear coat onto the wiring to ensure arcing doesn’t happen. Very cool device, while a bit pricier, well worth the piece of mind to make sure that new light fixture you’re installing doesn’t burn down the house ☺️

The connectors are now very expensive because aluminum wire hase not been used in houses since the early 70's. These are for aluminum to copper wire connections.

These are the same as what you get at the big box stores, only cheaper. Used to connect aluminum and copper wiring. These are special because they are filled with ox-guard or other brand name of black nasty material that helps contain the wire connections and reduce chance of fire. Copper and aluminum wiring expands and contracts at different rates and arching can occur leading to fires. These are rated to prevent this from happening.

When it’s not feasible to replace aluminum wiring, these work well and are an approved method for “pigtail-ing” copper wires onto the aluminum wiring. This enables use of a wider selection of modern receptacles and switches that are only compatible with copper. Very useful to have.

My house was originally wired with aluminum. I use these where the screw-in connectors are too big. I have also had copper wires installed for appliances that create heat.

These are very good quality and useful ! I use them with anti-oxidant joint compound and it has paid for itself ! Great value for the money !

Worked for what needed. A bit pricey-$6 a connector.

Works as expected!

Those twisters are doing its job!

It was not clear to me that this was a 2 pack for this price when the others were much larger packages. I got taken!
